Deterministic schemes for key distribution in wireless sensor networks

2008 3rd International Conference on Communication Systems Software and Middleware and Workshops (COMSWARE '08), 2008
In this paper, we propose a new security metric for measuring resilience of a symmetric key distribution scheme in wireless sensor network. A polynomial-based and a novel complete connectivity schemes are proposed and an analytical comparison, in terms of security and connectivity, between the schemes is shown.

A Combinatorial Approach for Key-Distribution in Wireless Sensor Networks

IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008
Sensor nodes are usually deployed in adversarial environments in which they are subject to compromise and revelation of critical information rendering the entire network useless. Therefore, secure communication of wireless sensor networks (WSNs) necessitates utilization of efficient key distribution schemes. Over the past few years, several works using

Study on key distribution scheme for wireless sensor networks

2010 2nd International Conference on Computer Engineering and Technology, 2010
For solving the issue of key distribution in the clustered sensor networks, proposed a key distribution scheme based on layers, in which base station sends the secret knowledge of member nodes to the cluster-header, and member nodes establish pairwise key with their neighbor nodes via cluster-header.

A lightweight key distribution mechanism for wireless sensor networks

SPIE Proceedings, 2008
Security is of critical importance for many potential applications of wireless sensor networks. In order to maintain secure communication throughout the network, it is of vital importance to maintain encryption key freshness by regularly distributing new keys to all nodes.

A novel key pre-distribution scheme for wireless distributed sensor networks [PDF]

Science China Information Sciences, 2010
A novel key pre-distribution scheme for sensor networks is proposed, which enables sensor nodes to communicate securely with each other using cryptographic techniques. The approach uses the rational normal curves in the projective space with the dimension n over the finite field \( \mathbb{F}_q \).

A Dynamic and Distributed Key Management Scheme for Wireless Sensor Networks

Proceedings of the International Conference on Internet of things and Cloud Computing, 2016
Ensuring key management in Wireless Sensor Networks has a vital importance, especially when sensor nodes have to communicate in hostile environments. In this paper, we propose a new simple and resource-aware key management scheme. The scheme is based on the idea that the initial pre-distributed key is not pre-loaded in all nodes to improve its ...

A Novel Key Distribution Algorithm in Wireless Sensor Network

2014 Sixth International Conference on Measuring Technology and Mechatronics Automation, 2014
This paper studies the E-G key pre-distribution algorithm principle, and a new key distribution algorithm based on the Blom key pre-distribution model is proposed. The nodes is deployed in a hexagonal area. Each cluster uses preshared key to establish key pair, Blom key pre-distribution model is used in the establishment of key pair among clusters. The

Distributed Key Certification Using Accumulators for Wireless Sensor Networks

2014
In this work, we propose a key certification protocol for wireless sensor networks that allows nodes to autonomously exchange their public keys and verify their authenticity using one-way accumulators. We examine and compare different accumulator implementations for our protocol on the Sun SPOT platform.

Distributed Energy Efficient Key Distribution for Dense Wireless Sensor Networks

2009 First International Conference on Computational Intelligence, Communication Systems and Networks, 2009
The recent research in Wireless Sensor Networks has led to a number of security schemes. The main requirement in Wireless Sensor Networks is not only security but energy efficient security due to limited resources. We propose an energy efficient key management protocol fully developed in TinyOS and tested in Avrora Emulator.

Agent-based Distributed Group Key Establishment in Wireless Sensor Networks

2007 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks, 2007
Wireless sensor networks are comprised of a vast number of ultra-small autonomous computing, communication and sensing devices, with restricted energy and computing capabilities, that co-operate to accomplish a large sensing task. Such networks can be very useful in practice, e.g.
